Purpose:
To evaluate the use of the resorbable polylactic acid polymer implants (Resorb X) in the management of orbital floor blow-out fractures as regards safety, cosmetic, and functional results.
Methods:
In a prospective, interventional case series, 22 patients with traumatic blow-out floor fractures underwent lower fornix transconjunctival repair using polylactic acid implant insertion over the defect without fixation. Orbital imaging was done preoperatively, at 1 month and 1 year postoperatively with orbital computed tomography with 2 mm cuts of axial, sagittal, and coronal scans. Outcome measures included the maximum vertical height of the orbit at the fracture plane and its changes over time.
Results:
At the final follow-up, both limitation of elevation and diplopia improved in 82% of cases, while 63.6% of cases showed improvement of enophthalmos. Radiological restoration of the orbital vertical height was recorded in 100% of cases without implant displacement at 1 month. However, after 1 year, a significant floor bowing was found in 45.5% of cases, which showed a strong positive correlation with preoperative defect size (r = 0.820).
Conclusions:
Resorb X mesh plates can be a good option for the safe reconstruction of orbital floor blow-out fractures. Good anatomical and functional results were obtained in small orbital floor defects. Late bowing under pressure may limit their use in medium-sized floor defects.
